Hi Axel,
I am here again. But with the solution :)
Your suggestions were very helpful. After reading your previous email about
the possible mismatch between the kernel module and the driver etc. I tried
to update nvidia driver downloading from their own website (just checked
whatever version of nvidia graphics card I have) and found that my nvidia is
not updated (as you suggested in this email).

So after downloading the file below, I just installed it after stopping the
X server.
sh NVIDIA-Linux-x86_64-100.14.11-pkg2.run
It then installed 32 bit opengl and then compiled the kernel matching with
the graphics card and may be removed some incompatibilities automatically.

Now opengl works fine and so does vmd.

Thanks again
Arnab
